(5.12) ANSI Escape Sequences

What ANSI escape sequences can be used?

ANSI escape sequences provide cursor and screen control in OS/2 Warp 

character mode sessions.  By default ANSI support is turned ON (although 

it may be turned off with the command ANSI OFF).  ANSI support is also 

available in DOS sessions if the device driver ANSI.SYS is loaded.  See 

the online Command Reference for details.

The following ANSI escape sequences are available:

 Key       

 ESC       Refers to ASCII code 27 (i.e. the Escape key) 

 #         Replace with the appropriate number 

 ....      Replace with additional attributes, if desired

 Escape Code Sequence          Function 

 Cursor Controls               

 ESC[#;#H or ESC[#;#f          Moves cursor to line #, column # 

 ESC[#A                        Moves cursor up # lines 

 ESC[#B                        Moves cursor down # lines 

 ESC[#C                        Moves cursor forward # spaces 

 ESC[#D                        Moves cursor back # spaces 

 ESC[#;#R                      Reports current cursor line and column 

 ESC[s                         Saves cursor position for recall later 

 ESC[u                         Return to saved cursor position 

 Erase Functions

 ESC[=#;7l                     Resets mode # set with above command 

 Keyboard Reassignments        

 ESC[#;#;....#p                The first ASCII code defines what is to be 

                               changed; the remaining codes define what it 

                               is to be changed to; strings are permitted. 

                               

                               Examples: 

                               ESC[65;81p - A becomes Q 

                               ESC[81;65p - Q becomes A 

                               ESC[0;68;"dir";13p - Assign the F10 key to 

                               a DIR command. 

                               The 0;68 portion is the extended ASCII code 

                               for the F10 key and 13 is the ASCII code 

                               for a carriage return. 

                               Other function key codes: F1=59, F2=60, 

                               F3=61, ... F10=68.

 You can use ANSI escape sequences in the PROMPT environment variable to 

 create complex command line prompts.  See the online Command Reference 

 (under PROMPT) for details.

 For example, if you have a color monitor, try editing your CONFIG.SYS 

 file so that

 SET PROMPT=$e[32;40m$e[1m[$P]$e[0m

 to obtain a more colorful OS/2 Warp command line prompt.  (Case is 

 significant in the example given.)  You can do the same for your DOS 

 sessions if you edit PROMPT in AUTOEXEC.BAT, assuming you have ANSI.SYS 

 loaded.  Note that the $i portion of your PROMPT will enable the help 

 line at the top of the window or screen.  It is not included in the 

 example above.
